To aZZ whom it may concern: openings (1 leads to the condensation-pipeg, Be it known that I, GEORG HUBER, a subarranged, preferably, inserpentines about the ject of the Emperor of Austria-Hungary,reoil-receptacle A, which pipe embouches into siding in the city ofVienna, in the Province a central channel g, preferably on the op- 55 5of Lower Austria, in the Empire of Austriaposite portion of the bottompart of the re- Hungary,have invented certain new and useceptacle A.

and of the discharge of oil. The oneof the Steam from the steam-supplypipe enters through bore or channel 0, channel d, and check-valve17zintothe condensingpipeg,from Where the condensing-water enters throughchannel 9 below the oil-column into the receptacle A on its lowest pointand thus lifts the oil-column, leading it out drop by drop throughchannel n and valve 12 to the nozzlepipe 7', from where the oil passesthrough the channels f and 0 into the valve-box, cylinder, &c. In thesame measure as oil drops off from the nozzle steam will enter into thereceptacle A, whereby constant lubrication is assured. lVhen all the oilin the receptacle A is used 'up, which is the case when pure water dropsoff in the tube h, then the valve k is closed, whereupon the water islet off from the receptacle A by the cock 8, and now the receptacle isfreshly filled with oil by removing plug Z) For locomotive-engines whichrequire lubrication for two engines I employ a modification of theapparatus, as shown in Fig. 3, provided with two dropping-pipes h h,which, however, do not embouch into channel 2), but communicate withconduits o 1:, leading to the slide-valve boxes. Live steam is admitteddirectly into the apparatus, which in this instance preferably isattached to the engine- I In this case the regulating- ,1

valves are arranged, preferably, in a horizontal position, and bothdrip-pipes h 72, may have eithera common feeding-supply channel, asshown in Fig. 3 in dotted lines, or each may have a separate channel 12.

Having thus described my invention, I claim 1. A steam-lubricatorcomposed of an oilreceptacle, a steam-condensing pipe provided with acheck-valve and communicating with the receptacle at the bottom thusraising the oil by condensed water, a small channel at the top of thereceptacle and a drip-nozzle consisting of a small pipe provided withsmall exits for the oil on its lower end, and a solid mandrel attachedthereto and ending in a fine point, substantially as described.

2. In a steam-lubricat-or an oil-drip nozzle composed of head 7L,cone-valve p, a small pipe '1' provided on its lower end with exit forthe oil, a solid mandrel ending in a fine point, and a sight-glass,substantially as described.

In testimony whereof I have signed this specification in presence of twosubscribing Witnesses.
